Notes
PGY-UFS4.0-PA, UFS Protocol Analyzer is the industry-first working and tested UFS4.0 Protocol Analyzer. It offers protocol data capture and debugging of data across MPHY, UniPro, and UFS protocol layers. It allows for instantaneous decoding of UFS, UniPro, and MPHY layers with the flexibility to correlate decoded data across these protocol layers. PGY-UFS4.0-PA supports PWMG1 to HSG5B data rates and two TX, and two RX lane decode. The active probe has minimum electrical loading on the device under test (DUT) and captures protocol data without affecting the performance of DUT. PGY-UFS4.0- PA Protocol Analyzer supports two-lane data. Comprehensive on the fly decoding of UniPro & UFS data enables validation of communication between UFS host and device.
PGY-UFS4.0-PA Protocol Analyzer allows Design and Test Engineers to obtain deep insight into UFS host and device communication. MPHY/UniPRO/UFS packet-based triggering allows specific protocol data capture and analysis. PGY-UFS Protocol analyzer instantaneously provides decoding of UFS, UniPro, and MPHY layers with a correlation to MPHY, UniPro, and UFS layers.

UFS 4.0 Protocol Analyzer (PGY-UFS4.0-PA) is the Protocol Analyzer with multiple features to capture and debug communication between the host and device under test(DUT). PGY-UFS4.0-PA, UFS Protocol Analyzer, a value-based analyzer in its class, offers capture and debugging of data across MPHY, UniPro, and UFS protocol layers. It allows for instantaneous decoding of the UFS layer, UniPro layer, and MPHY layer with the flexibility to correlate decoded data across these protocol layers.

Solder-down active probes allow probing of the MPHY test points. This allows the design and test engineers to capture UFS traffic between the host and UFS memory with high signal fidelity. Today’s test engineers need to test the use case scenarios in their labs that mimic real-life use cases. The PGY- UFS4.0-PA, UFS Protocol Analyzer has been designed to enable engineers to closely monitor and analyze the traffic between the host and the device while executing the various use case scenarios.
Test Setup
PGY-UFS 4.0-PA UFS Protocol Analyzer interfaces to solder down probe tips using mSMP Flexi coax cables. The active probe tips are powered by a power module which is powered by PGY-UFS4.0-PA. Protocol Analyzer is interfaced to host computer using USB3.0 interface. High-speed host connectivity and 16GB buffer enable continuous streaming of protocol data to host SSD and storage for a longer period of time. The software offers multi-view such as MPHY view, UniPro view, and UFS View. Each view lists the respective protocol packets and their details with a correlation of each layer for easy debugging. The lightweight Analyzer is easy to carry during field visits.
UFS Protocol Layer
PGY-UFS 4.0-PA Software can display each UFS packet parameter in a listing window. Right-click lists all the packet parameters for user selection. Users can color code the fonts or background color for easy identification of each UFS packet.
PACP And Unipro View
PGY-UFS4.0-PA Software separates the PACP packets in a separate view for easy analysis of power mode change packets and link to UniPro packets. Users can view the MPHY states stall, prepare, sync information in UniPro view apart from user selection for DL_Data and AFC/NACK Packet details.
Error Events, Search, and Filter
PGY-UFS3.X-PA Software does the live decode and lists all the events. The list of events is shown in this picture. Users can easily note the errors in captured protocol data. In large buffer capture, it become extremely difficult to locate the errors. But PGY-UFS3.X-PA software simplifies this by listing events while decoding the captured data. Search and Fliter allows you directly locate the error events or UFS or UniPro or PACP packet in the protocol listing windows. Filter-in Filter-out makes it easy to view the data of interest in the protocol listing window.
Comprehensive Protocol Analysis Using Multi-View
PGY-UFS4.0-PA UFS Protocol Analyzer provides a USB3.0 interface for host computer connectivity. High-speed host connectivity enables continuous streaming of protocol data to host HDD and storage for a long period of time. The software offers multi-view such as MPHY view, UniPro view, and UFS View. Each view lists the respective protocol packets and their details with a correlation of each layer for easy debugging.
PGY Protocol Analyzer’s easy-to-use interface reduces the protocol analysis time. Time-stamped view of protocol decode listing provides an easy view of protocol activities between the host and the device. At a click of a button, the user can view the decode of each packet and the intended function. Floating window software architecture allows the user to view each protocol layer on separate monitors for easy debugging. Autocorrelation of each selected packet from UFS to MPHY layers simplifies the debug activity
